Many-body emergent dynamics of QCD and its exact analogy to gravitational memory

Raju Venugopalan , Brookhaven National Laboratory
It was proposed about 25 years ago that the Regge limit of QCD could be described by a many-body classical effective field theory now known as the Color Glass Condensate (CGC). This conjecture was prompted by the phenomenon of gluon saturation, whereby many-body gluodynamics leads to the emergence of a semi-hard scale that screens color charge in the infrared. We discuss the structure of the CGC effective theory, emphasizing its efficiency in performing systematic high order computations in the Regge limit. We also outline a color memory effect in the CGC which bears an exact analogy to the gravitational memory effect that could be discovered by LIGO in the near future. This correspondence in turn prompts one to speculate that asymptotic BMS-like symmetries analogous to those in gravity may also apply in QCD's Regge limit, leading to novel insight into how pions form
